BUCKLE.

Specicaton of Letters Patent No. 22,352, dated December 21, 185.8.

To all whom t may concern:

Be it known that we, JorimT CUMBERLAND, of the -city and county of lNIobile, in the State of Alabama, and JAMES R. MOULIN- 'roo1;, of the city, county, and State of New York, have invented a new and Improved Buckle or Clasp, and do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a front view of the buckle. Fig. 2 is a back view. Fig. 3 is a front view of the part A of the buckle. Fig. l is afront view of the part B of the buckle. Fig. 5 is a section of the buckle taken through the center in the line y, Fig. l. Fig. 6 is a top view of t-he buckle.' Fig. 7 is a side view of the buckle with straps attached.

The nature of our invention consists in making the buckle in two parts, one of which slides upon the face of the other, and attached to each other by means of grooves or pins in such a manner as to allow of the requisite movement of the sliding part. The sliding part is made to bite upon the strap or article to be held, by means of the pressure caused by tightening the buckle. The strap to be held passes over a projecting edge upon the back of the sliding part and also through the slot in the stationary part and causes another projection on the front of the sliding part to bite against the edge of the slot in the stationary part through which the strap or article to be held is passed.

The same letters in the different figures refer to the same parts of the buckle.

A is the stationary part of the buckle or the part attached to the article permanently.

- B is the sliding part of the buckle.

C is a projection forward of the part B and forms one side of the opening through which the strap to be fastened is passed. The front edge of C is in some cases serrated slightly, to prevent the accidental moving of the strap G.

D is a projection backward on the part. B, and forms the other side of the opening through which the strap to be fastened is passed.

E, E, are two grooves in which the part B, slides formed by bending over the edges of the part A so as to leave a recess of the proper width between the parts bent over, and the face of the part A, for the part B to slide freely in. i

F is the slot in the part A by which the buckle is permanently attached to the strap H or article to be fastened. The lower edge of F is sometimes serrated slightly to prevent the accidental movement of the strap G.

G is the strap of cloth or other article to be held by the buckle, and is shown as passing over the projection D, and through the slots K and I where it is held. by the bite or pressure of the forward project-ion O on the part B, against the lower edge of the slot I in the part A.

H is the strap or article to which the buckle is permanently attached.

I is the slot in the part A through which the strap to be buckled is passed.

K is the slot in the part B through which the strap to be buckled is also passed.

The method of using the buckle is as follows; the part A is first fastened to one part of the strap H by passing it through the slot F and sewing the end fast to itself, and then the other strap G is passed through the slots I and K the part B, having been moved back so as to bring the two slots in line with each other. The end of the strap G is then drawn through the slot so as to tighten the buckle upon it. The pressure of the strap G upon the projection D causes the forward projection C to bite upon the strap G at the point where it passes over the front edge of the slot I in the part A and then holds the strap G so that it cannot be withdrawn by any pressure upon the end G of the strap G until the pressure upon it is slackened so as to allow the sliding part B to move back sufiiciently to bring the slots I and K in a line which is eected readily by simply pulling' upon the end G of the strap which at once brings the parts into line and allows whatever' tightening or slacking may be needed to adjust the article to be fastened by drawing the strap G farther through t-he buckle or allowing it to be withdrawn if necessary.

le claim as our invention- The buckle or clasp composed of the parts A and B or their equivalents substantially as described and for the purposes described.
